As seen from the above table, the purplish red outside line shielding rate of height of the present invention coating can reach very high purplish red outside line reflectivity, has extraordinary purplish red outside line shield effectiveness.Meanwhile, in coating, the proportioning ratio of each component has certain influence to purplish red outside line shield effectiveness, and wherein, ethanol plays diluting effect, and urethane plays matrix effect, polyamide resin solidification, and very few coating is inhomogeneous, do not have intensity, too much reduces the reflection function of material.The very few reflection function of Octabenzone and ferrite composite material is not strong, too much weakens coating intensity, damages on the contrary reflection function.Tenox PG too much reduces the reflection function of material.
Be more than preferred embodiment of the present invention, all changes of doing according to technical solution of the present invention, when the function producing does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
